A. X=y(z+rw)
B. X=rw(y-z)
C. X=rwy+z
D. X=rwy-z
Given the equation (x/y)-z=rw, we make x the subject of the formula as follows:
(x/y)-z=rw
Add z to both sides of the equation
(x/y)-z+z=rw+z
(x/y)=rw+z
Multiply both sides by y
(x/y)*y=y(rw+z)
X=y(rw+z)
Rearranging the equation results in:
X = y(z+rw)
Therefore, the Correct Answer is A.
